We are done with Week One of the Barry Bonds perjury trial -- where each time you leave the courtroom, you feel like taking a shower. There's no court on Fridays. So let's review the action to date, with a brief look ahead to Monday's next session:

It is still bizarre to see Bonds sitting at the defense table, so out of his baseball element and the world he once ruled. Bonds is dressed in a sharp suit, eating the occasional mint. He even yawned Thursday afternoon and closed his eyes, though he didn't appear to be napping.

I can see why prosecutors picked Steve Hoskins, the former friend and business partner of Bonds, as their first real witness. He wasn't exactly a strong presence on the witness stand, convincing at times but weak on others. Usually, the best witnesses are saved for a big finish, to leave jurors with the best impression.

Monday, we should get to hear from Bonds' former mistress, Kimberly Bell. And then will come a parade of former major leaguers with BALCO connections. I'm waiting for Benito Santiago. The funniest part of that 2003 audio recording of Hoskins' conversation with Bonds trainer Greg Anderson in the Giants' clubhouse was when Anderson paused in his discussion of steroid injections and said: "Hi, Benito." Shows you how frighteningly casual the steroid talk was on that Giants team.

Orchidometer. That will never be the Sesame Street word of the day. But it will be heard again in this trial after being introduced during Thursday's testimony by Dr. Larry Bowers of the United States Anti-Doping Agency. An orchidometer is a scientific device used to measure a man's testicles. What, you don't have one at home?

I think everyone senses where the orchidometer topic is going. Allen Ruby, Bonds' lawyer, tried to establish that using one is the only way to determine shrinkage. The guess is that Bell didn't have one when she allegedly saw the effect steroids had on Bonds' body parts. She will talk about that next week. (Understand what I mean about taking a shower?)

Another strange sight: Mike Murphy, the Giants' clubhouse manager, strolling down the courthouse hallway in a snazzy suit and tie. Not his usual working gear. Murphy is on the witness list (presumably to testify about Bonds' increasing cap size) but has not yet been called. Not sure when he will be. Hope it's before opening day. He has been with the team since 1958.

It's hard to estimate how much this is costing Bonds. Has to be in the millions. He has hired three top lawyers from all over the Bay Area. And they bring along a lot of staff. During the week, some are staying overnight in a downtown San Francisco hotel. And they probably aren't eating at McDonald's.

Dr. Arthur Ting, the well-known Bay Area sports physician, also has many questions to answer whenever he takes the stand. Hoskins said that in 1999, he was sent to Ting by Bonds, who wanted information about Winstrol, the steroid. The judge did not allow Hoskins to reveal what Ting told Hoskins -- but did allow the admission of page copies from a medical journal that Ting gave Hoskins. Also, Hoskins says that Ting told him after Bonds' elbow surgery that the injury could only have been caused by steroids.

During Ting's testimony, I'm sure he'll be asked about his half of these conversations. And he probably can't invoke patient-client privilege because Hoskins wasn't his patient.

Puzzling fact: Hoskins is a diminutive guy, well under 6 feet with a small frame. But his late father, Bob, was a 49ers defensive tackle for six seasons in the early 1970s and was listed at 6-foot-2 and 251 pounds. Steve's mom must have been a jockey.

Ruby's best moment Thursday: He induced Bowers to inform the jury that USADA people did not confirm that the "cream" and the "clear" were steroids until early 2004. Obviously, this was done so that Ruby can tell the jury that if USADA didn't know those were steroids, how could Bonds have been expected to know that in 2003 when he testified before the grand jury that he was unaware what he was taking.

Everybody who owns Barry Bonds memorabilia had better closely study those autographs. Hoskins testified that Bonds sometimes authorized him to sign contracts forging Bonds' signature. It's no leap to assume Hoskins did the same on other items. Such as baseballs. One contract called for Bonds to autograph a few thousand. Think he signed them all? Arouses my worst suspicions about memorabilia.

One man following these proceedings closely: Roger Clemens. He faces his own perjury trial this summer. So take that, you Bonds lovers who think the government is picking only on him.

Look, I understand why some people would say this is a completely frivolous case. But I don't agree. Full disclosure: I'm the son of a retired judge and attorney. I firmly believe that the foundation of our legal system is based on people telling the truth in court. And if the government suspects strongly that someone is lying under oath, it has an obligation to prosecute.

Yes, the USA has more important issues at the moment than Barry Bonds at the moment ... but if someone can lie in court about steroids without consequences, someone else could theoretically lie about murders or embezzlement and face no punishment. Where do you draw the line? Should action against a rich athlete be dropped just because he has the resources to fight every inch of the charge? Bonds could have settled this years ago by doing what Jason Giambi and other athletes did -- admit to steroid use, apologize and move on.
